AUSTIN, Texas -- Longhorns quarterback Jerrod Heard was being evaluated for a head injury Thursday night after being ruled out for the rest of the game against Texas Tech in the second quarter.
Heard took a hard hit on a third-down sack and was taken to the locker room for further evaluation.
Tyrone Swoopes has taken over at quarterback for the Longhorns, who are currently missing seven starters.
Three of Texas' top four running backs -- Johnathan Gray (foot), D'Onta Foreman (finger) and Kirk Johnson (leg) -- are sidelined with injuries, leaving freshman Chris Warren as its only option at running back.
